[JBoss-user] [JCA/JBoss] - Re: Not able to see uncommitted updates made within same ora
Did not get any clue turning trace ON. Also no warnings found. But setting auto commit to false on connection did the trick. Appears that auto commit set to true causes separate transaction per statement execution. Since default is true, still at a loss how it was working in dbcp.

[JBoss-user] [JCA/JBoss] - Not able to see uncommitted updates made within same oracle
Hello,
Code that worked fine under commns-dbcp is not working under jboss. Essentially
subsequent read after write in same transaction is not seeing the records written.
Oracle's default behavior is to be able to see updates made within same transaction
even though not commited. Not sure why we are seing this in Jboss.
Data Source config:
local-tx-datasource
| jndi-namemyDS/jndi-name
| connection-urljdbc:oracle:thin:myhost:mydb/connection-url
|driver-classoracle.jdbc.driver.OracleDriver/driver-class
| user-nameuser/user-name
|passwordpass/password
|
exception-sorter-class-nameorg.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter/exception-sorter-class-name
| track-statementstrue/track-statements
| /local-tx-datasource
Code snippet:
Connection con = null;
| ResultSet rset = null;
|
| InitialContext initctx = new InitialContext();
| DataSource ds = (DataSource)initctx.lookup(java:/myDS);
| con = ds.getConnection();
| if (con != null)
| {
| Statement stmt = con.createStatement();
|
| ..
| stmt.execute(insertQuery); //inserts records in a temp_keys table
| int updateCount = stmt.getUpdateCount();
| //This prints count fine
| logger.debug(Update count: + updateCount);
| String testQuery = Select count(*) as CNT from TMP_KEYS;
| rset = stmt.executeQuery(testQuery);
| //This Prints -1
| logger.debug(COUNT TMP TABLE: + stmt.getUpdateCount());
| if(rset.next()){
| //This prints 0
| logger.debug(COUNT of ROWS in TMP Table: + rset.getInt(CNT));
| }
|
Any pointers appreciated.
Tx
-Sib

[JBoss-user] [Management, JMX/JBoss] - JMX Notifications for clients behind firewall
Is it possible at all to get JMX notifications to work for clients behind a firewall. I am almost on the verge of giving up on this. I tried all invokers JRMP, Pooled and Http. For every one of these I'm able to reach my mbean on the server but notifications do not come back. I've used the RMIAdaptor on my client for all of these. Is this possible at all? Want to ask for one last time b4 I move on looking for some other solution to get my notifications to work. Thanks.

[JBoss-user] [Management, JMX/JBoss] - Re: RemoteMBeanServer.addNotificationListener hangs for a wh
incidentally changing the jboss-service.xml to pooled invoker in in jmx-invoker-adapter-server.sar seems to have resolved my hang problem. But notifications are not coming back. Don't see any exception either. There's probably more to than just changing it to pooled invoker. I kept the client code still the same. Do I need to change something else also. Any pointers would be greatkly appreciated. Also if someone can tell me what level of trace or debug to turn on to see why notifications are not coming back up that would be great. Just setting org.jboss to debug didn't help any. Here's what I did.

[JBoss-user] [Management, JMX/JBoss] - Re: RemoteMBeanServer.addNotificationListener hangs for a wh
Scott, Thanks for your reply. I have found the problem and it appears to be with our firewall situation. Well I found that connections initiated from server were being denied since our clients are behind firewall themselves. Opening up a client box did resolve this issue. But this is not an option for us unless we know which ports on the client the server is going to connect to. Can you suggest how to achieve notifications from server in a situation where client is behind a firewall. I am posting the thread dumps from the run that hangs. I hope you can throw some light on how to resolve this issue or some workaround.

[JBoss-user] [Management, JMX/JBoss] - RemoteMBeanServer.addNotificationListener hangs for a while
Hi, I am hoping someone can give me some pointers to a problem I'm having in production environment. Everything is fine in the development network. But JMX notifications are frustratingly slow in production. I have opened up all the ports that JBoss uses and still have the issue. I am using JBoss 3.2.3 Here's the jist of my code: Object ref = ic.lookup(jmx/invoker/RMIAdaptor); RMIAdaptor server =(RMIAdaptor) javax.rmi.PortableRemoteObject.narrow(ref, RMIAdaptor.class); MBeanServer mbeanServer = new RMIConnectorImpl(server); ... ... //This call hangs for a while b4 it goes thru. mbeanServer.addNotificationListener( lBean, lListener, (NotificationFilter) null, new NotSerializableHandback(lBean.toString())); Any ideas why in a firewall situation I am having this issue. Also the notifications from the mbean is equally slow to get to the client. Hoping if someone has faced this issue and resolved it would let me know how.
